Struct LegacyMessage 

pub struct LegacyMessage {
    pub id: String,
    pub topic: String,
    pub payload: Vec<u8>,
    pub sender: String,
    pub metadata: HashMap<String, String>,
    pub created_at: i64,
}

Legacy message structure (v0) for backward compatibility.

This is the original message format with binary payloads. New code should use Message instead.

Fields

id: String

Unique message identifier (auto-generated UUID).

topic: String

Message topic/type for routing or categorization.

payload: Vec<u8>

Binary payload data.

sender: String

Name of the sending agent.

metadata: HashMap<String, String>

Arbitrary metadata key-value pairs.

created_at: i64

Creation timestamp in microseconds since epoch.

Implementations

impl LegacyMessage

pub fn new( topic: impl Into<String>, payload: Vec<u8>, sender: impl Into<String>, ) -> Self

Create a new legacy message.

pub fn correlation_id(&self) -> Option<String>

Get the correlation ID for request/response tracking.

pub fn set_correlation_id(&mut self, id: &str)

Set a correlation ID for request/response tracking.
